Actually keeping the bacteria alive is better acheived by draining all the water. Keeping water in the tank kills the good bacteria and replaces them with anaerobic hydrogen sulphide (sewer gas) producing bacteria in a a short time. The good bacteria need moisture and oxygen to survive. They really don't need water and are natural to moist soil not just to well oxygenated aquatic environments. In unoxygenated stagnant water, they perish quickly. When the Cleveland Aquarium moved its fish to a new location, they experimented with different ways to keep bacteria alive before the move and found two ways that worked. One was an elaborate battery operated circulation system that fit into the bed of a pickup truck. The other was to drill small holes in the bottom of 5 gallon plastic buckets so that water did not puddle and turn the gravel anaerobic.TheeMon said:well i have sucessfully move about 1/3 of the tanks.
the reason i wanted to leave water in is to keep the substrate under water to keep bacteria alive. i just drained as much as i could untill it started hitting substrate then stopped... worked fine
Doane said:When I move my tanks I put all of my filter media in a 5g bucket with a lid and fill that with water. I then move tanks with nothing in them. (I am not SUPER anal if there are just a few specs of sand in the tank I don't sweat it but no more than would fit in one fist) I then put my fish into 50 gallon bins (also plastic) in the back of a U-haul. Those I use a DC/AC converter and run airstones in. I am moving in about a month and hope to document the ENTIRE thing and do a write up. Hopefully once I am done this will provide much needed advise. The secret is to not put your filter media in with your fish. (made that mistake ONCE and lost like 2 fish due to them getting whacked) I have been playing around some some new ideas as far as keeping bacteria alive and water movement. You'll all see in a month. I'll be moving 3 10 gallons a 20H a 20L a 40 Breeder, a 55g and a 120g. Should be interesting.
